Abstract :
A cavity-backed slot array antenna using a single waveguide fed sub-array is presented. A subarray consists of 2×4 slot elements backed by a single cavity. By proper choice of dimensions it is shown that the proposed antenna has characteristics of high radiation efficiency and broad frequency bandwidth. Antenna characteristics for the array antenna with 256 elements are measured in Ku-band.
